Dust in homes is composed of about 20–50% dead skin cells. [2] The rest, and in offices and other built environments, is composed of small amounts of plant pollen, human hairs, animal fur, textile fibers, paper fibers, minerals from outdoor soil, burnt meteorite particles, and many other materials which may be found in the local environment.

The aspirator creates a vacuum that draws wood dust up through the holes of the sanding pad. An innovative dust control system has been developed that uses additional exhaust and a slottedanding pad. [3] LEV for orbital sanders [3] Dust control plenum for orbital sander [3] A new dust control plenum has been designed for orbital sanders.
As such, the nature of occupational dust exposures can vary greatly by chemical composition, size, concentration, and toxicity to humans. Depending on the source, dust composition can include mineral dusts, heavy metals, respiratory sensitizers (chemicals that can cause allergic reactions such as asthma), chemical dusts, molds, spores, and more.
We'll admit that sometimes this room slips our dusting radar, but as it turns out, the bathroom is a key area where dust builds up fast (in other words: this room needs to be dusted as much as any ...
Wood dust is known to be a human carcinogen, based on sufficient evidence of carcinogenicity from studies in humans. It has been demonstrated through human epidemiologic studies that exposure to wood dust increases the occurrence of cancer of the nose (nasal cavities and paranasal sinuses).
Instead of humans being potentially exposed to a dose of toxic chemicals in black plastic utensils near the minimum level that the EPA deems a health risk, it's actually about one-tenth of that.
Coal ash contains many toxic substances that may affect human health, if people are exposed to them above a certain concentration in the form of particulate matter.So it is necessary to avoid situations in which employees working in coal-fired power plants or public members living close to coal ash landfills will be exposed to high coal ash dust concentrations.

Molds are ubiquitous in the biosphere, and mold spores are a common component of household and workplace dust. The vast majority of molds are not hazardous to humans, and reaction to molds can vary between individuals, with relatively minor allergic reactions being the most common. [ 1 ]
